TUSA's patented 3-D strap is a true three-dimensional design that snugly fits against the head's natural curvature. The 3-D strap offers unprecedented comfort and fit unlike standard flat mask straps.
Anti-Reflective (A/R) Lens Treatment
Standard glass lenses can reflect up to 15% of available light reducing vision underwater. TUSA’s Anti-Reflective (A/R) Lens Treatment decreases internal and external reflected light. This reduction increases light transmission to 95% resulting in significantly enhanced color, clarity, contrast and better overall vision underwater.
CrystalView Optical Glass
CrystalView optical glass lenses provide superior clarity, color and transmission of light over standard glass lenses used by the competition. Up to 15% of available light can be lost with a standard glass lens due to impurities and reflectivity. TUSA’s CrystalView lenses transmit 92% of available light to the diver for clear crisp vision. CrystalView lenses are used in all PRO models masks and also in the M-41 Freedom Quad.
Round Edge Skirt
TUSA's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.
Skirt Mounted Quick-Adjust Buckle System
The Quick-Adjust Buckle System incorporates a newly-designed low-profile buckle into the crystal silicone skirt of the mask. The result is a compact, lightweight, technologically advanced mask design that can be easily and quickly adjusted for a perfect fit.
UV Lens Treatment
Increased exposure to UV light can damage the eyes especially in marine environments where reflectivity is high. TUSA’s UV Lens Treatment provides 100% protection from harmful UVA and UVB rays. Blocking 100% of the ultraviolet spectrum (under 400nm) provides greater eye protection without sacrificing light transmission or vision.
